无法使用 Cypress 6.4.0 和 TypeScript 在 POST 请求中上传 pdf 文件

Question

我正在使用Cypress 6.4.0&TypeScript，我需要在请求正文中上传一个pdf文件。我的请求代码是：

我的请求主体代码是：

public async createAssetDocTest() {
let url = sharedData.createAsset_url + sharedData.assetA;
let response = await fetch(url
,
{
method: 'POST',
body: await requestbody.createAssetDocBody(),
headers: {
Authorization: sharedData.bearer + " " + adminTokenValue,
Accept: sharedData.accept,
'Content-type': sharedData.docReqContent,
},
}
);
expect(response.status).to.equal(200);
public async createAssetDocBody(): Promise<any> {
const file = sharedData.doc;
cy.fixture(file).then((pdfDoc) => {
Cypress.Blob.binaryStringToBlob(
pdfDoc,
sharedData.contentTypeValue
).then(async (blob: string | Blob) => {
const formData = new FormData();
formData.set(sharedData.document, blob, file);

const body = {
formdata: {
document: {
value: pdfDoc,
options: {
filename: sharedData.document,
contentType: null,
},
},
},
};
return body;
});
});
}

但是，该文件不上传文件&请求失败，并出现错误400。有没有更好的方法上传POST请求正文中的文件？在此处输入图像描述

解决了此问题！

主要问题是我的Cypress版本太旧了。升级到9.7.0

然后添加以下代码：

public async createAssetDoc(): Promise<any> {
cy.fixture("pic location", "binary")
.then((file) => Cypress.Blob.binaryStringToBlob(file))
.then((blob) => {
var formdata = new FormData();
formdata.append("document", blob, "pic location");
const url = "your url";
cy.request({
url,
method: "POST",
body: formdata,
headers: {
Authorization:
"bearer" + " " + token,
Accept: "application/json",
"Content-Type": "multipart/form-data",
},
}).then((response) => {
expect(response.status).to.equal(201);
expect(response.statusText).to.equal(
sharedData.fileUploadStatusText
);
const finalResponse = String.fromCharCode.apply(
null,
new Uint8Array(response.body)
);
return finalResponse;
});
});
}
